摘要

Comprehensive, reliable and timely data on literacy rate is important for formulating policies and improving the state of literacy level in a country. The purpose of this study is to estimate age specific adult literacy rates (ASALRs) for male, female and both sexes population of urban area in Bangladesh. And, to fit some mathematical models to these ASALRs and their forward cumulative distribution. For this, the secondary data on literacy number and corresponding population obtained from population census 2001 are used to fulfill these objectives. Quasi Newton Method is employed for the estimation of these models. F-test, t-test and cross validity prediction power (CVPP) are also applied to check the accuracy of these fitted models. It is found that all the curves are showing decreasing with increase of ages. After all, it is found that ASALRs for male, female and both sexes of urban area in Bangladesh follow third degree polynomial model. And their forward cumulative distribution follow second degree polynomial model. It is observed that the models are well fitted in accordance with t-test, F-test and CVPP. The stability of all these models is more than 97%. The result of this study will help to increase literacy rates of urban area by using effective steps or strategies.
